Web1. You need to rotate around the X axis to have "up-down rotation", Z axis if you want "roll rotation", and Y if "left-right" rotation. Rotate the "front" (or look at vector) and "up" vector around the desired axes. Make sure to rotate those vectors before translating the camera. If you applied your rotation and translation then recreate the ... WebDescription. Creates a rotation with the specified forward and upwards directions. Returns identity if the magnitude of forward is zero.
